The deep green towers and pyramids of Eastern Red Cedar are an enduring and widespread presence in abandoned fields and open roadsides all across eastern North America. Appearing in a variety of shapes and sizes, it tends to grow in large colonies, and most commonly forms either a tall, narrow spire or broadly conical tree. It grows slowly to moderately fast depending on soil and climate, and may eventually become a sizeable tree, potentially living for hundreds of years. Its aromatic, scale-like, evergreen foliage is dense, lush, and prickly to the touch, and may develop bronze tones in the cold temperatures of winter. Mature specimens develop sturdy, fluted trunks with appealing, silvery-brown bark which peels off in long, papery shreds. The fragrant, red-colored wood has long been prized for its beauty and resistance to decay. Female plants bear large quantities of small, blue, berry-like cones which are an important source of winter food for many birds.This hardy, adaptable evergreen requires full sun and well-drained soil of low to moderate fertility. It is highly tolerant of drought, heat, cold, and poor, rocky soils, but cannot tolerate soggy conditions or standing water. An excellent wildlife plant, eastern red cedar is beautiful whether planted as a specimen, screen or windbreak. Numerous cultivars exist, all of which are attractive, versatile, low-maintenance additions to the landscape. (source: learn2grow.com)

1. Place your juniper seeds in a plastic container of water and leave them to soak for at least 12 hours.
2. Remove the seeds from the water and make a tiny nick in each seed, using a sharp knife. This process is termed scarification and is an important step towards germination.
3. Plant the seeds in trays. Place each seed in a 3/4-inch deep depression in the soil. Cover the seeds with potting soil, but don't compact the ground over them. Keep the soil in the potting trays moist.
4. Place mulch over the seedlings.
5. Cover the mulch with grit to dissuade moss and algae from growing over the potting soil.
6. Keep the seeds at a temperature of 39F (+2-+4C) for 3 months and then transfer them to a room with a temperature of 70F/-+20C. This process is termed stratification and the seeds will begin to germinate at this warmer temperature.
7. Keep the seedlings in a shaded area for the first year of their lives. There will be sporadic germination of these seeds over a two to three-year period. It is important to realize that each individual seed from the same pod has its own degrees of embryo viability. Certain seeds will germinate at once, while others will go into a dormant state. Seeds also have "chemical locks" that degrade to allow germination at different times. These mechanisms afford the tree the best chance at survival, so don't be concerned if not all of your seeds germinate at the same time.
